Political Parties and Elections Bill

My query is about the previous part of the plan, the point at which the provision of identifiers is not yet compulsory. I have a number of concerns about that. What the Minister is announcing is immensely important, and by the time identifiers become compulsory we must have learned as much as possible about what the pitfalls might be. How will the system work during that run-up period? Will different areas do different things? Unless they are, surely we will not be able to learn the possibilities of the scheme. For example, a student library card might be an identifier in a student area, but not in a different area. What will happen so that we get experimental data in that period?
